Dermatological Diseases

There are over 3,000 different skin conditions and diseases, including psoriasis, vitiligo, and atopic dermatitis.

Psoriasis is a chronic autoimmune disorder that causes cells to rapidly accumulate and affects the surface of the skin. The extra skin cells form scales and red patches, or flares, which are itchy and sometimes painful. The National Psoriasis Foundation reports that psoriasis affects approximately 7.5 million people in the U.S., which accounts for over 2% of the domestic population. Globally, this skin condition is estimated to afflict over 125 million people.
Vitiligo is an autoimmune condition causing the skin to turn white due to the loss of pigment from the melanocytes, cells that produce the pigment melanin, which gives skin color. Vitiligo affects 1-2% of the population globally.
Atopic dermatitis, a chronic eczematous skin disease, can result in itchy, red, swollen, and cracked skin. There are approximately 17.8 million people in the U.S. suffering from atopic dermatitis, making it one of the most common inflammatory skin diseases.



Pharos is a powerful excimer laser used by physicians as a tool to treat chronic skin diseases, including psoriasis, vitiligo, atopic dermatitis, and leukoderma. It delivers highly concentrated 308 nm ultraviolet light to the affected skin without burning or ablating the skin.

Pharos offers significant benefits to patients. The targeted nature of Pharos treatment allows the operator to spare healthy tissue from exposure to the ultraviolet light making the treatment faster and safer than some other forms of phototherapy, or light therapy. Treatment with Pharos differs from topical treatments, such as steroids and vitamin D derivatives, which may require a frequent ongoing application. Treatment with Pharos also differs from pharmaceuticals treatments, which may be associated with systemic side effects.



Coverage may vary according to patients’ individual plans. Talk to your physician’s billing staff for details about your insurance coverage.

The Pharos is the only treatment that has ever worked for my scalp. I've tried injections, creams, shampoos, oral medications, and none of it worked. But, since I started the laser treatments, my scalp has cleared more than 85%. There is no pain or side-effects.

I've had moderate psoriasis since I was a child. My doctor told me he could help me achieve remission with the Pharos excimer laser. I was skeptical, but now, for the first time in 10 years, I can wear short-sleeves and a bathing suit. I am experiencing remission for the first time in my life.

Tracy M.

I've been an excimer laser patient for a few years. Recently my physician switched from offering the other excimer laser to the Pharos laser and I am experiencing even better results.  My Pharos treatments not only provide quicker results but also an overall improvement in my condition.
I now have the ability to use the Pharos laser in many more areas of concern.  With the other laser, I could only treat my scalp because my skin would darken if it was used on any exposed skin. With the Pharos, because it is specifically targets at the problem area, I am able to treat many more areas and not have an unsightly darkening of my skin.  And while the other laser was warm and at times, even hot while receiving treatment, the Pharos does not transmit any heat during treatment.

Patients who are excellent candidates for the excimer laser are patients with more localized plaque psoriasis of elbows, knees, buttocks, or as an add-on adjunctive therapy after full body NB UVB exposure in our phototherapy box. The excimer laser is very efficient in clearing flexural crease psoriasis, as well as resistant psoriasis of the scalp and genital areas. We often use it in combination with an optimized topical regimen such as steroids and vitamin D3 foams.

The excimer laser is a very important part of the treatment armamentarium for vitiligo. The combination of pigment stimulation and safe local immunosuppression gives rates of success of up to 70%. There is hope for vitiligo.
